Andrew Mountbatten-Windsor has reportedly sued Thames Valley Police over his February arrest related to his alleged providing of confidential information to deceased sex offender Jeffrey Epstein.
The man formerly known as Prince Andrew asked a U.K. judge to determine whether officers acted lawfully toward him when they took him into custody nearly eight months ago, Politico and the Telegraph reported Sunday.
Thames Valley Police officers arrested Mountbatten-Windsor, the younger brother of King Charles III, in connection to his links to Epstein, who died in 2019.
Files related to the federal probe into Epstein the Justice Department (DOJ) released earlier this year showed Mountbatten-Windsor apparently sharing confidential information with Epstein while he served as the U.K.’s special representative for international trade and investment.
Mountbatten-Windsor had a longstanding relationship with the disgraced financier, and the late Virginia Giuffre alleged that Epstein and Ghislaine Maxwell trafficked her to the former Duke of York, who forced her to have sex with him three times — including when she was 17.
Mountbatten-Windsor has denied those allegations, and settled a civil lawsuit Giuffre brought against him in 2022. Giuffre died by suicide in April 2025.
When police arrested Mountbatten-Windsor earlier this year, he became the first British royal to receive such a fate in nearly 400 years. Investigators released Mountbatten-Windsor after 12 hours of questioning, with police saying at the time he remained under investigation.
The Hill has reached out to Buckingham Palace regarding the reported lawsuit by Mountbatten-Windsor. The king stripped his brother of his royal titles in October, after files House lawmakers released in October 2025 revealed details about Mountbatten-Windsor’s ties to Epstein.
U.K. investigators have faced difficulty in their probe of Mountbatten-Windsor due to the DOJ refusing to hand over the unredacted version of the Epstein files, Politico and the Telegraph reported.
The High Court of Justice in London will reportedly hold a private hearing this week to determine whether to release certain documents related to Mountbatten-Windsor’s lawsuit.
